Walsh debuted her diamond ring over the weekend at the Kennedy Center Honors in Washington, D.C. Grammer and the former Virgin Atlantic flight attendant were among the stars in attendance.

Grammer, 55, and Walsh, 29, announced in August that they were expecting their first child together. That came a little more than a month after the actor's third wife, Camille Donatacci, filed for divorce after 13 years of marriage citing irreconcilable differences (following revelations no less that Grammer fathered a child while they were still together). Sadly, Walsh suffered a miscarriage six weeks later.

Here's hoping they get back on track with the honeymoon.

Grammer already has an 8-year-old daughter and 5-year-old son with Camille, plus two daughters from previous relationships.
